Building Molecules Virtual Lab

Goals of the lab:
1. Understand the difference between atoms and molecules and recognize how how different atoms can come together to make various molecules.
2. Learn several new molecule names and their chemical formulas.
3. Recognize that the subscript describes how many atoms are in a molecule and that if there is no subscript that means that there is one of that type of atom in a molecule.
4. Recognize that the coefficient is a number which describes how many of a particular molecule is present.

Click on the image below to download and run the virtual molecule lab. It takes a few minutes to download and run, so be patient. 

Build a Molecule
Click to Run

If clicking on the image does not work you can go to and click on "run now."

Have fun making lots of different types of molecules and collecting them all.

Powers of Ten

This classic film shows the power of "adding a zero." It starts off looking at a one meter square picnic scene near the shore of Lake Michigan. The camera pulls back to reveal 10 square meters, than 100, then 1000 then 10,000 etc... until the viewer is at the edge of the known universe many millions of light-years away from Earth. Then the viewer gets pulled back into the picnic scene... finally into the man's skin, into a blood vessel and eventually into a carbon atom in the man's DNA.

You can watch the film at this link.

This movie is introducing our basic chemistry unit. In order for us to understand the universe and the living things in it (Bio, after all, means life) we must understand the matter of which they're made. Since all living things are made up of atoms and molecules we need to understand how these basic building blocks of matter interact.

Origins: How Life Began Movie

You can re-watch the movie, "Origins: How life Began" at 
The site will show you a couple of ads before the movie starts, but the complete movie will play once the commercials are over.

Answer the following questions about the movie.

Use the movie “Origins, How Life Began” to answer the following questions. If you need more room, use the back of the paper. Use full sentences.

1. What happened when another planet the size of Mars slammed into the early Earth?

2. According to a 17th century “recipe” for life that includes a dirty garment and wheat, what will form in 21 days?

3. Describe the Earth as it existed about 4 billion years ago.

4. When do scientists think that life first began on Earth?

5. What are “snottites?”  What are they made of? Why do scientists need to wear gas masks when searching for snottites?

6. What four chemical elements are in most life forms?

7. How did Stanley Miller try to simulate the formation of early life?

8. How could the ingredients of life have come to Earth from space?

9. How did scientist Jennifer Blank prove that amino acids could have survived the heat and pressure of smashing into the Earth on a meteor?

10. How do the bacteria (really archaea) that live deep underground survive? How often do these underground bacteria reproduce?

11. What is a “stromatalite?”

12. How long did bacteria dominate the Earth before more complex organisms developed?”

13. Write a 1 – 3 paragraph review of this movie. What do you think about this movie and the information you learned from it? How does it make you feel about life on Earth?

Six Kingdoms Classification Project

Your mission is to fill out the "Six Kingdoms of Life" chart (handout). For each of the six kingdoms fill in "yes" or "no" in each column based on the characteristic listed at the top of the column.

Remember kingdoms have many different species in them so some kingdoms might have organisms that have different forms of a characteristic listed. For example in Kingdom Animalia there are both Herbivores and Carnivores, so you'd put a "yes" in both of those columns for Animalia.

While you may work together at the computers be careful to do your own work on your chart. Don't just put what someone else has because they have it... you must confirm the accuracy of your research from a reputable source (see below) rather than just from your friend in class.

In order to fill out your chart you can use information sources such as your class notes, the AGS Biology Text Chapter 15 Pp. 457-500 and the websites listed below.

The Six Kingdoms

Prokaryotic vs. Eukaryotic

Autotroph vs. Heterotroph

Herbivores, Carnivores and Decomposers

Sexual vs. Asexual Reproduction

Antibiotic Resistance Animation

Watch this animation to find out why we need to be careful when using antibiotics. When we use antibiotics unnecessarily or when we don't finish taking the course of antibiotics the doctor prescribes, we can actually create bacteria that are immune to the antibiotic. Click on the following link, read the page and then click on the "watch the animation." If you have speakers or headphones you can listen to the narration, if you don't have speakers or headphones click on "step-through" to read as the animation steps through.

Another very interesting video about antibiotic resistance that is affecting US soldiers in the Iraq war is viewable at this link:

Evolutionary Events Timeline

A great source for information on the various species for your evolutionary events timeline is  which is a wiki that people are creating to attempt to catalog every species on earth.

Use the search box to find examples of various species. Type in "jawless" to find images of jawless fish. If you then click on "multimedia" when the search results come in you can see images and video clips.

You can also just search google images for various species, but wikispecies has some great stuff.

Lorenzo's Oil RAFT assignment - Due Tuesday 4-12-11

Write a letter to Lorenzo's doctor. 

Role - Lorenzo’s parents (Michaela or Augosto Odone) 
Audience -  Dr. Nikolias who put the ALD boys on the no-fat diet to see if that would help their symptoms.
Format - A business letter
Topic - Why ALD boys need to not just stay on the low-fat diet, but need to start taking “Lorenzo’s Oil” (use evidence to convince Dr. Nikolias that boys MUST start taking the special oil you've discovered.)

Use the following underlined words in your letter.

Adrenolukodystrophy (ALD)
Long Chain Fatty Acids (C24 and C26)
Lorenzo’s Oil is made of Oleic Acid (C18) and Erucic Acid (C22)

The letter should be typed or written very neatly using standard English grammar.  You can see instructions for and an examples of business letters at the following links.

You may make up the doctor's address and your own return address. Be sure to put your real name and class period somewhere on the letter, since I can't give credit to Michaela or Agusto Odone. 

You can find out more about ALD at the following sites:

Lorenzo's Oil - Some people make their own miracles.

The movie Lorenzo's oil is the true story of how one family uses science to find a way to treat their son when he gets the debilitating disease adenoleukodystrophy (ALD). The research the doctors were doing was taking too long, so Lorenzo's parents identified the problem which caused the disease and tested their hypotheses about how the disease could be treated. Boys who get ALD now use the treatment that Lorenzo's parents invented.

If you were absent during the movie you can watch it for free on HULU

Here are a couple of obituaries of Lorenzo Odone who passed away the day after his 30th birthday... 22 years after the doctors predicted he would die.

Water intoxification: Hold your wee for a wii contest

Take a look at this short MSNBC news story about Jennifer Strange and her death by hyponatremia.

This link describes the sports medicine concern with hyponatremia that occurs in athletes who sweat a lot during an event, and then drink large amounts of water. Jennifer was not sweating like an athlete, but her body reacted in a similar way.

CBS News also did a story a few days later explaining a bit more about the consequences for the people who worked for the radio station.

It turns out that the DJs were joking about a person who died from water intoxication two years prior to their Wii contest... so they knew it was dangerous. The radio station was sued by Jennifer Strange's family and had to pay them quite a bit. The following article from the LA Times newspaper gives the details.

Mitosis = Somatic Cell Division

Mitosis is the process of cell division for eukaryotic cells found in multicellular organisms.  All cells come from existing cells and mitosis is how most cells divide. The only eukaryotic cells which do not divide by mitosis are sex cells a.k.a. gametes a.k.a sperm and egg cells.

The following links are to sites which can help you understand how mitosis works. The sites combine images, text and animation. Look at each site to best understand how the process works.
